You can download the HTML version of the Beta Installation Guide as a tar.gz file from this page:
http://fedora.redhat.com/docs/fedora-install-guide-en/
Unzip the file, and open the index.html in your Web browser.
The system that generates the HTML documentation will hopefully be able to generate good quality PDF files in the near future, but this relies on some development work with the necessary Open Source product (Apache FOP).
